DATA FUNCTIONS Keys
The Data Functions keys can be divided into two groups; those which affect
measurements (REF SET, METER, AVG, HI LIMIT and LO LIMIT), and those
which affect numeric entry fields (INCR
÷10, INCR SET, INCR×10, Up-arrow,
Down-arrow). For measurements, the Data Functions enable the programmer to
change the way measurements are calculated and displayed, and provide
measurement limit detection. For numeric entry fields, the Data Functions enable
the programmer to set, scale, and change the field’s increment value. Each Data
Function is described in detail in the Test Set’s User’s Guide.
Refer to the
“Number Measurement Syntax” on page 177 for full command syntax.
Guidelines for Using Measurement Data Functions
• Data Functions are turned ON and OFF for individual measurements. The GPIB Data
Function commands must immediately follow the GPIB command for the individual
measurement. For example, to turn the AVG Data Function ON for the Audio
Frequency Analyzer Distortion measurement, the following command string would be
sent to the Test Set:
OUTPUT 714;"MEAS:AFR:DISTN:AVER:STAT ON"
• Attribute Units (AUNits) are used with the Data Functions to specify the units-of-
measure for numeric data which is read or set through GPIB. Refer to “Attribute Units
(AUNits)” on page 81.
• Data Function settings, such as Number of Averages or Reference value, are retained if
the function is turned off. The setting values are initialized or changed under the
following conditions:
• The Test Set is turned off.
• The Test Set is PRESET.
• A saved register is recalled.
